Great pricing. When I am ready to upgrade, I plan on doing business with you all again. You value customers and that is greatly appreciated. Thanks for everything.

Outbound Power did a great job on n communication

Outbound Power did a great job with communication and answered all my presale questions. Shipping was prompt - and was patient with me during a small snafu when my neighbor was being “helpful” and took one of the boxes and neglected to tell me. Great prices too!

Review of EcoFlow DELTA Pro Ultra X Whole-Home Backup

I purchased the Delta Pro Ultra X with two batteries at the end of 2025 from Outbound Power to get the best price. All three components arrived intact in three separate heavy duty boxes with ample custom molded padding to protect the units from shipping mishaps. I stacked the 3 units on the included caster tray in a new tiny home, and used the unit after a firmware update to my satisfaction. After using the unit for a short while, I charged the unit with a Honda EU3000i gas generator. A week later I installed two solar arrays, totaling 4400 watts with 2 sets of (5) 440 watt panels. I live in Southern California, so this allowed me to be fully charged in an hour or two of full morning sun. The unit has been powering the tiny home which came with a 50A shore power connection. I ran a circuit from the wall nearest the EcoFlow under the tiny home and connected to power panel via the shore power 50A outlet, by removing the outlet and splicing in the new circuit. The unit will run the tiny home no problem and has been on since the end of 2025. I may consider two more batteries after running all my consumer calcs to be 100% off grid, all electric, while satisfying San Diego County's 4 day battery reserve capacity for permitted off grid application such as mine. I'm very happy with this unit. I run Starlink, the refrigerator, an on demand propane water heater (at this time) and a minisplit, plus an inductive cook top, oven, washer/dryer, lights, etc without any issues. The simplicity of installation is peace of mind, and being plugged into the sun feels good every day. Outbound power has reached out and offered to assist if the need should present itself. So far so good!
